Removing a Standard SIB or SIB Version B

To remove a standard SIB or SIB version B, follow this procedure:

1.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. See “Preventing
Electrostatic Discharge Damage” on page 47.

2.

Take the SIB offline by using one of the following methods:

Press and hold the

ONLINE/OFFLINE

button on the SIB faceplate for about

five seconds until the

OK

LED is not lit.

Issue the

request chassis sib offline

command. For example:

user@host> request chassis sib offline slot 0

NOTE: When you bring an active SIB offline, the spare SIB becomes active and
transitions to the

Online

state.

3.

Loosen the captive screws (using a Phillips (+) screwdriver, number 2) on the
ejector handles on each side of the SIB faceplate.

4.

Flip the ejector handles outward to unseat the SIB.

5.

Grasp both ejector handles, pull firmly, and slide the SIB about three-quarters of
the way out of the chassis.

6.

Place one hand underneath the SIB to support it and slide it completely out of
the chassis. Place the SIB on the antistatic mat.

CAUTION: Do not stack hardware components on one another after you remove
them. Place each component on an antistatic mat resting on a stable, flat surface.
